I just witnessed a shooting (killing?)

LOL @ the whole concept of "warning shots." That's the most retarded idea ever, especially for a cop. Everyone knows cops carry guns, they don't need to fire into the air (risking killing an innocent bystander) just to show everyone they have a gun.

Soldiers at checkpoints fire warning shots even though they're carrying large, very visible, weapons. I'm sure there are situations when a cop could shoot a warning shot too, but they probably don't involve the target having a gun.
